knewin.com Listed by ALP-001 Ransomware Group

On March 30, 2026, Brazilian media intelligence company Knewin appeared on the leak site of the ransomware group ALP-001. The listing includes 176.5 GB of internal files exfiltrated during a ransomware attack on the firm, which maintains what it describes as Latin America’s largest media monitoring database.

Reported Details of the Incident

Public reporting on the ALP-001 leak site indicates that Knewin’s stolen data was posted with a deadline of April 3, 2026 at 23:57:50. The company, which reported $52.5 million in revenue, provides media monitoring, big data analytics, and artificial intelligence services to clients across traditional and digital channels. Available reporting describes the exposed material as internal files; the exact number of individuals whose personal information may be contained in those files remains unknown. No independent verification of the data volume or contents has been published outside the attackers’ own claims.

Why This Matters for You and Your Family

When a company that holds large volumes of media, marketing, and competitive intelligence data is breached, the information can easily include client lists, contact details, and personal identifiers that tie back to ordinary people. If your name, email, phone number, or address appears in Knewin’s records—perhaps through a brand mention, press release, or marketing campaign—those details may now be in the hands of criminals. For you and your family this means heightened risk of phishing, identity theft, and unwanted exposure long after the initial breach fades from the news.

Credential leaks like this one frequently cascade into account takeovers on other services where the same email and password are reused.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. Once internal documents are public, opportunistic actors scrape them for email addresses, usernames, phone numbers, and any linked social media handles. These fragments are then stitched together with data from previous breaches to build detailed profiles. What begins as a single company breach can quickly expand into a doxxing chain that reveals home addresses, family member names, and even children’s online gaming accounts. The speed and automation now common in these attacks mean the window between initial exposure and targeted harassment or fraud is shrinking.

ALP-001’s Publicly Known Track Record

Public reporting attributes ALP-001 with emerging in late 2024 as a ransomware-as-a-service operator. The group has claimed responsibility for attacks on organizations in multiple countries, typically gaining initial access through phishing or exploited remote desktop protocols, exfiltrating data before encrypting systems, and then pressuring victims with both encryption and public leak threats. Notable prior victims include mid-sized firms in technology, manufacturing, and professional services sectors. Their standard playbook involves setting short payment deadlines—often only a few days—followed by incremental data releases if demands are not met.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what chains back to the Knewin exposure.
• Rotate any password you used on knewin.com or related services and enable two-factor authentication through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than months.
• Cover the household with DoxxScan family protection that extends to your children’s gaming accounts, which often become targets when credential leaks create doxxing chains.
• Let remediation specialists handle the time-consuming work of sending takedown requests to data brokers and monitoring platforms that republish the stolen information.

The Knewin breach is a reminder that data collected by marketing and media intelligence firms can affect the privacy of everyday families who never directly signed up for their services. Taking concrete steps now limits how far this incident can reach. DoxxScan by GalaxyWarden delivers continuous monitoring across more than 13.1 billion+ breach records and over 100 platforms, AI-powered identity-chain mapping that connects scattered online handles to real identities, and hands-on remediation by specialists who manage takedowns for you and your entire household, including children’s gaming accounts that frequently become part of these cascading attacks.
